Flip Fluid Waterfall – Particles, Part 3

When returning the the object view and going into the EmitterGeo node one thing that you notice when the create_surface_volume node is visible is that there is no particular movement or flow to the particles they just randomly emit from the gird which is unrealistic.Screen Shot 2013-12-20 at 11.53.50Here is a video that displays exactly how the particles look at present they have the appearance of an untuned TV but I will begin to change this as I progress through the tutorials.

In order to give my particles more motion and a different flow I need to create a mountain node done by using the tab menu typing in mountain and then placing the node on the path from edit1 to create_surface_volume node. In the image below is a messier view of my particles.Screen Shot 2013-12-20 at 11.55.34If I change the view from create_surface_volume to the mountain node this is what I see a rugged piece of geometry that I can play about with to get the correct motion for my particles.Screen Shot 2013-12-20 at 11.57.13The first edit I make is to the offset of the mountain1 node were I write an expression $FF/20 which takes the frame number and divides it by 20.

Here is a video to show the effect of adjusting the height of the mountain and adding an expression to the offset of the node.  As you can see it as more of an up and down motion to it like oceanic waves.

When returning to the create_surafce_volume node and making this visible you get the appearance of the particles in the video below which shows the effect that the mountain1 node is having on the particles (create_surface_volume node).
